Each year, tattooed devotees come to Wat Bang Phra temple, a place famous for its tattoo masters, to pay their respects to the art of Sak Yant, in a special ceremony known as Wai Khru. Attended by tens of thousands of people, the event becomes quite a spectacle when the animal spirit possessions begin.

At one point, a loud and frightening growl is heard from somewhere in that sea of people, but only foreigners seem to react to it. Then monkey sounds are heard, and people start running towards the temple - specifically towards the shrine of Luang Poh Pern, a respected tattoo artist who served at Wat Bang Phra – waving their arms in the air and yelling like crazy. They are in fact being possessed by the animals tattooed on their bodies. If they have a tiger tattoo, they start growling, if it’s a snake, they start crawling on the ground, but eventually they all start running like crazy toward the shrine.
